69-467 6.0mm Dia. x 21.0mm FL; Plano-Convex Lens Laser V-Coat 785nm
This is a 6.0mm diameter, plano-convex lens with a focal length of 21.0mm, specifically designed for use with a 785nm laser and featuring a V-coat. The lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. The plano-convex shape, where one side is flat and the other curved, is ideal for a variety of applications, particularly where a collimated beam is required.
The lens has a center thickness of 1.42mm and an edge thickness of 1.0mm, providing a good balance between weight and optical performance. The effective focal length (EFL) is 21.0mm, which is the distance from the lens to the point where the beam converges or diverges.
The lens features a V-coat on both the front and back surfaces, specifically designed for 785nm lasers. This coating enhances the lens's performance by reducing reflections and increasing transmission, making it ideal for laser applications.
The item data also includes the radius of curvature (R1) of the curved surface, which is 10.85mm, and the back focal length (BFL), which is 20.06mm. The BFL is the distance from the back surface of the lens to the focal point.
